I usually go to gamma if I feel the person ( skin ) doesn't have enough key light and doesn't pop - so I would put a soft power window on the subject ( person that is talking ) and just bump the gamma up a bit. That subtle bump of gamma helps make the viewer look at the subject. I have also done the opposite in concert footage where the exposure is good on the stage lighting but the faces are almost blown out - so then reducing the gamma can tame the skin and not affect the black level.

I really like how you make videos about uncertainties i’ve had during grading, but couldn’t quite put into a question. I would love it if you would talk about log midtones wheel, I’ve found it sometimes very useful for pushing color and exposure. I’m curious how that functions and how a Senior colorist might use it.

Nice video Cullen, I have a question for you or anyone else in this community. When I imported my Dji drone footage into Davinci Resolve 18.1.4 studio without any nodes. The footage was so grainy unbelievable noise. But I know for a fact my ISO was set at 100, & F4.0. SS60. Here's the sad thing, it looked perfect when viewing it on my iPad. Same good results on my iMac pro. When I put it in FCPX, it had Zero noise on the clip. So what's going on in DR 18.1.4 Studio that's causing the noise?

Thanks Cullen. When in ACES (cct), which control would behave like gamma behaves in display referred between 0 and 1? In ACES cct, I find offset works well for exposure but raises black. Thanks👍

Where would you play with your Gamma or work your Gamma/Lift/Gain in your node tree? Would you have that in Node 7 or would that be in your Balance Node? Or would that be a thing in your two secondaries Nodes underneath?

Are you talking about Lift Gamma and Gain knobs or the wheels? Is there a difference on the control surface?
@RafalGendarz
@RafalGendarz Жыл бұрын
If I know what it does to the curve is there any benefit to using the knob instead of building that curve where I have more possibillity to shape that curve?
@gagegarza
@gagegarza Жыл бұрын
I’m curious about this too. Is there a specific reason to use the primary wheels over the curve?

It is simpler. And it is easily repeatable.

The knob maintains a certain smooth relationship as you move it up or down. You could definitely make the curve manually but you might find yourself introducing unwanted effects if you manipulate in a certain way

But that’s Gamma in the generation. I’d like to think it has some photometric elements to it that made it so sophisticated and output clean operations. Now, is Gamma today, and here in resolve the same as it was back then? Like, does it have the same mathematical operations? Or do we need to modify our today’s Gamma to get it to match?
